To extract an object, you use tools in the Extract dialog box. First you draw a highlight that marks the edges of the object, and define the object's interior. Then you can preview the extraction and redo it or touch up the result as needed. When you extract the object, Photoshop erases its background to transparency. Pixels on the edge of the object lose their color components derived from the background, so they can blend with a new background without producing a color halo.
